NASA astronaut Don Pettit has posted another set of stunning shots, this time showing clouds as youve never seen them before.Captured from the International Space Station (ISS) some 250 miles above the surface of Earth, the clouds unique look is due to the the stations alignment with our planets day/night shadow.Recommended VideosLiving in the Twilight Zone, Pettit wrote in a post on social media. Our orbit on the space station now is aligned with Earths day-night shadow thus we see neither full day nor full night. This is the best time to photograph clouds under low-angle lighting.Please enable Javascript to view this contentLiving in the Twilight Zone.

The DIY astrophotography tool allows for the capture of sharper images of city lights at night as the device compensates for the stations movement relative to the Earths surface. It can also be used for long exposures of the night sky captured from back on terra firma, producing sharper images (without star trails) by counteracting Earths rotation.Editors Recommendations
